Water purification tank and water purifier comprising same

Abstract

A water purifier that purifies water to provide purified water may include: a purified water tank accommodating the purified water; and a discharge port discharging the purified water to an outside of the water purifier. The purified water tank may include: a tank main body that provides an accommodation space for accommodating the purified water; a discharge buffer part having an inlet which communicates with the accommodation space so that the purified water in the accommodation space flows in the discharge buffer part, the discharge buffer part extending in an up-down direction; an outlet tube including an insertion portion extending downward in the discharge buffer part to discharge the purified water to the discharge port through a discharge flow path; and a gasket extending from the insertion portion to an inner peripheral surface of the discharge buffer part to reduce sloshing of the purified water in the discharge buffer part.

What is claimed is: 
     
         1 . A water purifier that purifies water to provide purified water, the water purifier comprising:
 a purified water tank for accommodating the purified water, and   a discharge port for discharging the purified water to an outside of the water purifier,   wherein the purified water tank includes:   a tank main body that provides an accommodation space for accommodating the purified water;   a discharge buffer part having an inlet which communicates with the accommodation space so that the purified water in the accommodation space flows in the discharge buffer part, the discharge buffer part extending in an up-down direction;   an outlet tube including an insertion portion extending downward in the discharge buffer part to discharge the purified water to the discharge port through a discharge flow path; and   a gasket extending from the insertion portion to an inner peripheral surface of the discharge buffer part to reduce sloshing of the purified water in the discharge buffer part,   wherein the tank main body includes a plurality of partition wall members for partitioning the accommodation space into a plurality of accommodation spaces,   the plurality of partition wall members are spaced apart from each other in the up-down direction,   one end of each of the partition wall members is supported on an inner wall of the tank main body and the other end of each of the partition wall members is horizontally spaced apart from the inner wall of the tank main body by a predetermined distance, and   wherein the discharge buffer part further includes a communication hole,   the discharge buffer part communicates with an uppermost accommodation space among the plurality of accommodation spaces partitioned by the plurality of partition wall members through the communication hole, and the communication hole is provided above the gasket.   
     
     
         2 . The water purifier of  claim 1 , wherein a lower end of the insertion portion is disposed below the gasket. 
     
     
         3 . The water purifier of  claim 1 , wherein the purified water tank further includes an inlet part that is connected to an upper portion of the tank main body and guides the purified water into the accommodation space,
 the inlet is provided below the gasket and communicates the discharge buffer part and the accommodation space, and   the purified water in the accommodation space flows to the discharge buffer part through the inlet.   
     
     
         4 . The water purifier of  claim 1 , wherein the gasket includes one or more through-holes formed to penetrate the gasket in the up-down direction. 
     
     
         5 . The water purifier of  claim 1 , wherein the outlet tube further includes a sealing portion that seals between the insertion portion and the discharge buffer part to prevent gas from flowing between the insertion portion and the discharge buffer part. 
     
     
         6 . The water purifier of  claim 1 , wherein the gasket is fixedly supported on any one of the discharge buffer part and the outlet tube. 
     
     
         7 . The water purifier of  claim 1 , further comprising:
 an inlet valve that selectively blocks a passage through which the purified water flows into the purified water tank.   
     
     
         8 . The water purifier of  claim 7 , wherein the discharge flow path is open to communicate with the outside of the water purifier, and the flow of the purified water to the discharge port is controlled by opening and closing of the inlet valve. 
     
     
         9 . A purified water tank comprising:
 a tank main body that provides an accommodation space for accommodating purified water;   a discharge buffer part having an inlet which communicates with the accommodation space so that the purified water in the accommodation space flows the discharge buffer part, the discharge buffer part extending in an up-down direction;   an outlet tube including an insertion portion extending downward in the discharge buffer part to discharge the purified water to a discharge port through a discharge flow path; and   a gasket extending from the insertion portion to an inner peripheral surface of the discharge buffer part to reduce sloshing of the purified water in the discharge buffer part,   wherein the tank main body includes a plurality of partition wall members for partitioning the accommodation space into a plurality of accommodation spaces,   the plurality of partition wall members are spaced apart from each other in the up-down direction, and   one end of each of the partition wall members is supported on an inner wall of the tank main body, and the other end of each of the partition wall members is horizontally spaced apart from the inner wall of the tank main body by a predetermined distance; and   wherein the discharge buffer part further includes a communication hole, and the discharge buffer part communicates with an uppermost accommodation space among the plurality of accommodation spaces partitioned by the plurality of partition wall members through the communication hole.
